I have used these on some Ferd projects I got talked into being involved with. You'll have to use the OE plate and threaded adapter, but they are a nice piece. I think they have a locating tab that could be removed, but otherwise can be rotated 360*. They keep the filter close to the block. And best of all, FMS still sells them.

If the results don't match the theory, change the theory.
